Patented Apr. 26, 1910.

, To all whom it may concern:

Be it known that I, WILLIAM B. INoL1s,a citizen of the United States,residin at the city of Pawtucket, in the county 0 Providence and Stateof Rhode Island, have invented certain new and useful Improvements inSpraying Ap aratus, of which the following is a speci therein to theaccompanying drawing.

This invention relates to a spraying apparatus and has for its object toprovide an improved device fol automatically mixing insect destroyingchemical soap, powder or solution with water, and to finally dischargethe mixture in the form of a spray or stream into the trees orshrubbery.

A still further object is to provide a mixing chamber of novel type atthe end of the nozzle which is adapted to thoroughly blend, combine or'mix the solution with the water under pressure before it is forcedtherefrom in the form of a spray.

With these and other objects in view, the invention consists of certainnovel'features of construction, as will be more fully de scribed andparticularly pointed out in the appended claim.

In the accompanying drawings: Figure 1 shows the spraymg apparatuspartly in section, the tank being adapted to retam a chemical soap orother insect destroyer chemicals, that is soluble in water, the samebeing dissolved and mixed with inflowing water in this tank which is aapted to soli i tank. The inlet pi e 3 is adapted to roject in theproper proportions and forced u into the nozzle where it is againdiluted an combined or mixed with the water,'under pressure, andsubsequentlydischarged from the nozzle. Fig. 2- is a side elevation of asimilar apparatusthe tank being in section and showmga iston locatedtherein adapted to be forced upward by a pressure of water to dischargethe contents of the tank into the spraying nozzle. Fig. 3- is anenlariged sectional view of the spraying nozzle.

' eferring to the drawin s, 1 designates a lain tank or receptaclea ated to receive insect destroying chemicals. s ecially preared chemicalsoap is referably de osited or cake, as illustrated at 2, on the bottom0 the down into this tan through the hea 4, its

' lower end being preferably curved as at 5 so as to start the water torotate or to receive .a

whirling motion around the sides of the tank cation, reference being hadand over the face of the soap to mix with or make a suds from the soap,which suds or mlxture is forced outthrough the outlet pipe 6 whichextends down into said tank through the head 4. v I

The nozzle 7, see Fig. 3, is'adapted at one end 8 'to screw onto theordinary hose 9 through which the water under pressure is connected. Theopposite or discharge end of this nozzle 10 is made into the shape of ahollow ball forminga mixing chamber 11. A small discharge aperture 12 isprovided in the end of the ball through which the mixture is forced. Afeature of this invention is that a narrow inlet passageway 13 is formedin the wall of this nozzle leading from the inlet point 1 L into themixing chamber, the wall of said channel being curved as at 15 towardthe water inlet opening 16 so that as the water enters the mixingchamber it will take a whirling motion around the wall of the same so asto draw in the solution and thoroughly mix the same with the water underpressure before discharging the'whole through the openin At the inletoint 1 1 is an outwardly extending teat or oss threaded to receive theattaching'end of a glass sight feed 17, the opposite end of said feedbeing provided with a shut-off or controlling valve 18. Near the screwattaching end of the nozzle is an outlet 19 controlled by a valve 20which is connected by' a pipe 21 to the storage tank below. The supplyor return from the said tank leads up through the pi e 22, controllingvalve 18,.and sight feed 1 through the channel 13 into the mixingchamber 11.

The apparatus illustrated in Fig. 2 is similar in effect andconstruction to that illustrated in Fig. 1, the only difference beingthat the tank inlet pressure pipe 21 instead of being connected in thetop of the storage tank, as shown in Fig. 1, is connect: ed into thelower portion of said tank, which tank is provided with a piston 23arranged with suitable packing on its edges and having a steadying guiderod 24 extending up through its head 4.

The operation of the device is more particularly described as follows:In some cases it is desired to use a chemical soapand in other cases achemical solution is preferred. a

When the chemical soap is used the same is preferably deposited in a.water-ti ht receptacle, as illustrated in Fig. 1. he water underpressure from the supplying hose is allowed to pass down through thepipe 21 into the tank Where it receives a whirling motion over thesurface of the soap, dissolving the same a little at a time and making asuds of the proper consistency, the suds being then forced out throughoutlet pipe 22'into the nozzle where it is again mlxed with the waterunder pressure and finally discharged through the nozzleopen:

ing onto the trees or shrubber When a solution is used it is preferab ydeposited bottom of the tank beneath the in a tankcontaining a piston,such as that illustrated in Fig. 2, the water pressure like that in Fig.1 being allowed to pass through the controlling valve 20, pipe 21, butinstead of into the top of the tank, is admitted to the iston wherebythe solution is forced from t e-upper portion of the tank through theoutlet pipe 22 into the. nozzle to be mixed with the water underpressure and finally discharged as desired. A feature of this lastarrangement is that the solution will remain the same strength orconsistency until the whole'has been discharged from the tank.

The storing tank 1 of my improved ap-' paratusis provided with ears 25'to which a strap 26 is connected for the purpose of slinging the tankonto the back or over the shoulders'of. the operator so that he may'carry the tank with him, if desired, when and rested u on the ground orcarried on the back of t e operator, leaving the nozzle entirely free tobe manipulated in the hands of the operator, which arrangement is foundmuch more effective and satisfactory than where the solution carryingtank is connected rigidly to the distributing nozzle.

I do not'restrict myself to the use of this device for spraying treesand shrubbery, as the same may be used for-washing windows or for anypurpose for which it may be adapted. V

The device is simple and inex ensive in its construction andextremelyefilbient and effective in its 0 eration.

Having thus escribed my invention, what I claim as new and desire tosecure by Letters Patent, is:

In a spraying device, a storage tank, a spraying nozzle, said nozzlebeing formed in one of its walls with a narrow passage 'way one end ofwhich extends through the said wall of the nozzle and has connectionwith thetank, the wall of the passage way at its opposite end beingcurved upwardly toward the water passage ropef of the nozzle, a hollowball carried y the nozzle at its discharge end and formed with aperipheral discharge opposite said curved wall, means to connect thenozzle to a water supply, and means connecting the tank'with the waterpassage proper of the.nozzle.-
